Otolaryngologists of the Jefferson Voice and Swallowing Center perform an examination of the esophagus known as transnasal esophagoscopy (TNE), which is used to find the causes of voice and swallowing problems such as laryngopharyngeal reflux.
A TNE is an in-office endoscopic evaluation of the esophagus without sedation.
What Does Transnasal Esophagoscopy Involve?
The entire procedure takes just 10 minutes and involves the insertion of a thin endoscope with a tiny camera on the end to visualize your vocal folds, larynx, esophagus and other structures of the throat. The results can help to diagnose esophageal strictures, inflammatory conditions of the esophagus and even cancers.
